| Abstract | ||
| Background: Dental amalgam fillings interact in a complex way with the environment in the oral cavity as they are subjected to chemical, biological, mechanical, and thermal forces. These forces change the restoration’s appearance and properties, causing metal ions, amalgam debris, non-metallic corrosion products, and mercury released into the oral cavity. The aims of this study were Measure the concentration of mercury in saliva of children in relation to the number of amalgam fillings before and after chewing and measure the continuous release of mercury vapor from amalgam fillings in children and its relation to gender and age. Materials and methods: The sample consists of 51 children between 8-10 years of age and they were divided into three groups according to the number of amalgam fillings they have in their teeth (1st group children didn't have amalgam fillings in their teeth, 2nd group children had 1-2 amalgam fillings, 3rd group children had ≥3 amalgam fillings). Then saliva samples were collected from each child before and after chewing of sugar free chewing gum in sterilized disposable cups. Results: The results indicated that minute amount of mercury were continuously released from amalgam restorations and the release is accelerated after stimulation (chewing).Also the results demonstrated a positive correlation between the number of amalgam fillings and mercury concentration in saliva, mercury in saliva of children who didn't have amalgam fillings in their teeth may come from other sources such as air, water and food. There was no relation between mercury concentration in saliva of children and the gender and age of children | ||
